While most of the wooden hull has long since disintegrated from the shipwreck, copper that sheathed the hull beneath the waterline as a protection against marine-boring organisms remains, leaving a copper shell that retains the form of the ship. The copper has turned green due to oxidation and chemical processes over more than a century on the seafloor. Oxidized copper sheathing and portions of the draft marks are visible on the bow of the ship. The grey strip covering the stem is lead.
